This will help improve and reduce the amount of garbage in new topics.
And it will increase the
amount of garbage reply or comment in that thread.
1. If your new message has written 20 pages of reviews and answers - 5 merits.
2. If Your topic received 30 pages of feedback and answers - 5 more merits.
3. If your topic received 50 pages of feedback and answers - 10 more merits.
There will be 2 scenario if we apply this (or maybe more),
1. Lets say "User A" create a topic and want to earn merit, so he create a lot of account and reply on his own thread to earn merit.
2. He can try to start bounty and pay user to reply his thread. So, he can earn merit.
I maybe wrong, but from what i see from thread that have a lot pages, some of them are reply the same answer again and again (well, not all thread) and some of user probably doing copy-paste or plagiarism. So, this is not good idea, sorry.
